Fraunhofer Center for Silicon Photovoltaics CSPIt is not yet clear exactly how high Germany's demand for green hydrogen will be in the future. However, it is clear that demand will amount to several hundred million tons of hydrogen per year. The goal of the National Hydrogen Strategy is to build up as much as 5 GW of electrolysis capacity by 2030 in Germany alone – in the new coalition agreement, the expansion target was raised to 10 GW.
This requires efficient, durable, robust, inexpensive, and scalable electrolysers. Although large electrolysers that operate efficiently and over long periods of time are already available on the market, their manufacture is still largely manual. This is time-consuming, cost-intensive, and prone to errors. The series production of electrolysers that can be modularly adapted to their respective locations would be a significant step forward – also in terms of making green hydrogen competitive.
The H2Giga flagship project is therefore committed to the development of series production of electrolysers – and is open to all technologies. Together, established electrolyzer manufacturers, suppliers from various technology sectors—including many small and medium-sized enterprises—as well as research institutions and universities are advancing existing electrolysis technologies.
Abstract
Industrialization of electrolyzer stack production at the cell component and stack level through an industrializable, product-oriented concept, improvement of technical and economic properties, and development of industrial production processes.
Research topics IMWS
Coordinated, cross-scale, 2D and 3D microstructural characterization and evaluation of active materials and catalyst-coated membranes to identify relevant structures and degradation mechanisms.
Focus
Catalyst-coated membrane (CCM) and the 3-dimensional structure of the catalysts and their change during operation.
Methods
SEM, TEM, EDX, CT, XRD, XPS, ToF-SIMS, AFM, ESEM ... - Development of the methodology is part of the project
